Energy Science &Engineering, EarlyView.Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Market Consumption and Hidden Consumption: A Test for Substitutability [PDF]
In this paper we perform an empirical analysis on the relationship between private consumption and underground economy for the Italian case. We find that private market consumption and underground (or hidden) consumption may be defined as ”complementary ...

THE UNDERGROUND ECONOMY AND MONEY LAUNDERING, ECONOMICALLY DESTABILIZE FACTORS, BANKING BUT ALSO SOCIAL [PDF]
The desire of each of us is to earn as much money in good faith to achieve the goals which we intend to. But this depends on several factors, such as training, ability, experience and luck sometimes.

Energy Science &Engineering, EarlyView.This paper introduces a novel resilience‐based reward‐penalty scheme (RPS) for electricity grids facing high‐impact, low‐probability (HILP) disasters. By modeling the costs of proactive asset immunization against reactive RPS penalties, our analysis conclusively demonstrates that long‐term investment in grid resilience is the more economically rational

Recovery Factor of Pure Helium Injection in Depleted Gas Reservoirs and Its Influencing Factors
Energy Science &Engineering, EarlyView.This study employs compositional numerical simulation to systematically investigate the effects of injection rate, production rate, storage duration, and injection‐production scheme on pure helium recovery in depleted gas reservoirs. Low injection rates reduce viscous fingering while high production rates maximize near‐wellbore helium extraction ...

Energy Science &Engineering, EarlyView.A novel combined cooling and power generation system is proposed by integrating organic Rankine cycle (ORC) with an absorption heat transformer, which is driven by combining geothermal energy and data center's waste heat. The system using R601a yielded the best overall performance, achieving an exergy efficiency of 40.34% and an annual cost of 130.29 k$
